Just had a centerforce clutch and pressure plate put in my 1996 LT4 by a very reputable and long established performance shop. Now find out they do not have much experience on LT4's.
Horrible vibration from drive line now. They checked around and some chevy dealers said never resurface a LT4 flywheel. (which they did). They then called a Corvette specialty shop who said no problem if the shop doing the resurfacing has a special jig that was made for this flywheel. The shop they used for resurfacing does have that jig and it is the same shop the Corvette specialist said he uses.
Questions: Do you or do you not resurface a LT4 flywheel? If not, what do you do? Do you just purchase a new one from GM?
If so, is there any special engine/flywheel balancing procedure that needs to happen?
Any ideas out there? Of course, could have gotten a bad clutch or pressure plate but how do you tell?
FYI, balance the driveshaft and replaced U joints. Vibration happens standing in neutral, rolling, clutch in or out so think that eliminates anything after the tranny.
Please send suggestions. Thanksad ad
